The Correlations between Horizontal and Vertical Peripheral Refractions and Human Eye Shape Using Magnetic Resonance Imaging in Highly Myopic Eyes.

The aim of this study was to determine the relationship between relative peripheral refraction and retinal shape by 2-D magnetic resonance imaging in high myopes. Thirty-five young adults aged 20 to 30 years participated in this study with 16 high myopes (spherical equivalent < -6.00 D) and 19 emmetropes (+0.

Bilateral corneal erosion due to retail purchase of unfitted prescription contact lenses: a case report.

Purpose: We report a case demonstrating the importance of trial fitting before the dispensing of prescription contact lenses.

Methods: The patient was an 18-year-old computer-using experienced hydrogel lens wearer who ran out of contact lens supply. The patient purchased a brand new box of daily disposable lenses from a retail store having known his back vertex power.

Mistaken diagnosis of keratoconus because of corneal warpage induced by hydrogel lens wear.

Purpose: We report a case of corneal warpage secondary to hydrogel lens wear that was initially mistaken as a case of keratoconus.

Methods: A 26-year-old Chinese female hydrogel lens wearer presented with an interest in refractive surgery. After topographies and pachymetries were performed, keratoconus was initially diagnosed for her right eye and suspect keratoconus diagnosed for her left eye.
